To all whom it may concern:

Be it known that I, PEARL 'N. Jones, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Door-O crating Mechanism for Passenger-Cars, 0' which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional plan view of the rear platform of a passenger car, the section being taken on the line I-I of Fig. 2. In this figure, the entrance doorsare shown closed, while the exitvdoors are in theiropen positions; Fi 2 is a vertical section on the tine II"II 0 Fig. '1 Fig. 3 is a detail view of a portion of the: door-operating mechanism; Fig. 4 is a detail view showing the pivot roller for one of the doors; Fig. 5 is a plan view of the car step; Fig. 6 is an elevation of a portion of one of the doors; Fig. 7 is a perspective view showing a portion of one of the doors and a portion of the upper track-for the doors; Fig. .8 is a detail sectional view showing part of the door-operating mechanism; Fig. 9 is a diagram illustrating the door movements; and Fig. 10 is -a diagram shosving a modification.'

Th s application is a division of my pending application Serial No. 533,357,filedv December 16, 1909.

The present invention has more particular relation to the means-for operating the en: trance and exit doors of the .car, the doors being so arranged and operated that in both their and closedpositions, they are sub; '"st'antl without projection beyond the side" lines ofthe car' and the opening and closing movements'b effected in such a way as to encroach b ittle lipon the space I A further objpct of my invention is to provide a dooreparating mechanism which -="and,yvhich will now be described, it being. premised, however, that various changes. may be made in the details (if oonstractionv an arrangement of the various parts, without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the numeral 2 designates the (platform of a car structure which is inclose or vestibuled atone side and at the"rear, as shown at 3.

4 is an opening communicating with the interior of the car and which is without doors.

5 designates the car step arranged at one side of the platform or vestibule.

6.designates a bent rail or guard supported by the vertical posts 7 8 and'9, and which separates the entrance space or passage 10 from the exit space or passage 11.

12 designates two doors which control the exit, and 13 two other doors which control the entrance. These doors extend -from a point near the car roof downwardly to the floorof the car step 5. In order to give clearance in turning corners and to bring these doors well within the side lines of the car, the vestibule and platform are of gradually decreasing width toward the rear end and .the doors, together with the step, are

preferably set in the inclined plane of the side lines of the vestibule. Each door is provided at its upper end with a bracket 14', secured thereto and carrying aflanged roller '15, which is mounted to travel between and upon parallel track .bars16, as best shown in Fig. 7. 'The top of each 'doorisalso rovided with a roller '17 which is adapts "to travel on a portion 18 of the track, which extends m-- wardly at an obtuse angleto the track rail 16. .The lower edge portion of each door is also provided with the two antifriction guide .rollers 19, which are arranged to travel in the can; step ways or grooves in the floor of 5, each of these ways or ooveshav'ing a longitudinal portion 20, an another portion 20, extending inwardly at, an oblique angle to the portion 20, and correspo ding to the portions 18 of the upper tree to the outer or closing'ed e ot each door is a.

s.- Connected t link 21, the two links H rom each pair of] doors being connected at' their inner ends to a head 22, which is, intu n, connected to a slide23, mounted onlthe-parallel slide rods 24-. It will be understood from Fig. 1, that one pair of the slide r0ds'24sis provided for .the exitdoors and. a -similar pair for the:

entrance -doors.

The. slide 23 hich is connectedto th'e'exit doors, is connectedby a link 25' with. a crank arm 26, on a sprocket Wheel .27, which is.

This. rod or, post is 'journaled at its. upperand lower ends to act asj-a shaft and is provided with an operatin handle 30,,within convenient reach of' t e conductor who stands adjacent to the railing 6. The slide '23 which controls the entrancefdoorsis {conn'ected hy-zilink 31 with a crank arm 32,

V 5 which is rigidly secured-to asleeve 33,1oosely mounted on the rod'or post'B, and which is provided with an. operatingihandlelri, ad

acent .to the handle ,30, and also within conve'nient-reach of the conductor, j

The operationrof th will rbereadily understood by reference to the diagram shown in Fig.-39. In thisfigure, the exit doors'arek shown as open in full linesgwhile the entrance doors are shown in theiriclosed positions; thejiactuating connections for the respective doors being also-partially shown in their proper (position. 1 theenoons-vtdbeclosedand thatitis de; themgthe conductor grasps the handle: v thereby rotating the sleeve 33 on the rod' or post 8. This causes't-he crank arm .32toactuate the links 31, and thereby theflcorresponding slide 23. This movesthe "slide 23 outwardlyon the guide rods 24;,-and

' on the. pivots formed by the rollers 15 and i the correspondin ,bottomrollers 19. ,Attlie isame .tin'ie' the] 061's turn on these pivots,

the :slide' .backwardlyand inwardly on the 40- ro er's 1,7 ]and"corresponding bottom rollers 19, on the angular portions 18 and 20 of the tracks or ways, and "untilthey assumewthe full open position. This "full'open position corresponds to' the. open position shown for the exit doors in Fig. 1. In 'cl0s'ng the doors, the op'eratio'n'is the reverse, t e slide I '23 being movedback intothe position shown in Fig. 1; The exit doorsarewperatediin the same inannerby means of the handle-30. This movement of thedoors'ca uses the grab handles lh to be on the inside of the doors when closed, so that they can not be grasped from the outside. g

It will he observed that atno time during the openin and ,closin -moven1entof-thedoorsddt eir 'outere ges projectvbeyond the side lines of the car; also thattheir moyementis such inopen' and closing as g to encroachf but little upon t e entrance and texit 's acesor passagesw Each pair of doors isrun er the 'separate and completerccntrol of the conductor, who; usually stands ,within the bent portion 6. of the railing or' guard 6, for-thepurpose of collecting fares.

The bend or 0H- set35 arranged to fit around the post or r0d.9-, when the exit doors are; closed, 1n such a manner as to bring the centers of the connections between-tithe wheel, 27* and the slide 23 into such relation as to secure the doors ih=their closed positions. These centers, which are designateda, b and c, in F g; 1, are also brought into such relation when the any tendency for them to accidentally move toward their-closed positions.

The bend or ofiset 26 in the link 31 acts in a similar manner with res t to'therodor post 8, as will be seen :in igrlg By the described arrangement of the doors, in which' they are made to eiten'd to @point adjacent to the outer edge of the hey efiectively prevent. access, to the soiisjnmping upon the stepwhen jthe'car is doors have been opened.
